摘要
从模型及真机试验结果出发 ,叙述混流式水轮机一般的水力故障形式 .研究了尾水管的水力振动特点及振动随运行工况而变化的情况 .
From the model and prototype test result, hydraulic f au lts in francis turbines were introduced. The characteristics of hydraulic vibrat ions in draft tubes and variation of vibrations with operation conditions were s tudied. A method for monitoring the hydro-vibration in draft tube and diagnosin g the fault based on the frequency and amplitude of hydro-vibration was introdu ced.
